Photobioreactor for microalgae cultivation having arc-type partition structure for forming vortices

摘要

The present invention relates to a photobioreactor for microalgae cultivation having a bubble circulation structure, which allows gas flowing into a cultivation space to generate a vortex and thus circulate microalgae, thereby improving cultivation efficiency of the microalgae.;A photobioreactor for microalgae cultivation according to an embodiment of the present invention includes a cultivation panel major body having the cultivation space into which the microalgae are injected to be cultivated; a gas supply pipe provided at a lower portion of the cultivation panel major body to pass through the cultivation space in a transverse direction and thus discharge inflow gas; and at least one vortex forming partition extending in a transverse direction from an internal wall of the cultivation panel major body and formed to have an arc shape and thus cause a vortex to an ascending current of gas supplied through the gas supply pipe.

1. A photobioreactor for microalgae cultivation, comprising:
a cultivation panel major body having a cultivation space into which microalgae are injected to be cultivated and support ribs formed at regular intervals on an external surface thereof; a gas supply pipe provided at a lower portion of the cultivation panel major body to pass through the cultivation space in a transverse direction and thus discharge inflow gas; and at least one vortex forming partition extending in a transverse direction from an internal wall of the cultivation panel major body and formed to have an arc shape and thus cause a vortex to an ascending current of the gas supplied through the gas supply pipe, the support ribs being formed at intervals corresponding to the location of the at least one vortex forming partition, such that the support ribs prevent deformation of shapes of a front surface cover and a rear surface cover due to a water pressure generated according to filling of a cultivation solution or the microalgae in the cultivation panel major body and distortion of the cultivation panel major body through the ascending current of the gas.
